Durin awoke at Mount Gundabad in the Misty Mountains during the Years of the Trees. He journeyed South through the wild until he came upon Mirrormere (Kheled-zâram in Khuzdul). Looking upon mysterious stars set like a crown reflected in its surface, he took this as a sign, and there in the caves above the lake, founded a great city. This was Khazad-dûm, later called Moria, and for many years it was the greatest Dwarven city in Middle-earth.

Durin was the founder of the Longbeard house, which became known as Durin's folk. These were the Dwarves chronicled by Tolkien in the Second and Third Ages. The Longbeards believed that Durin would return to them seven times, and in each reincarnation he will again be named Durin and reign as King. He did have six descendents that were named Durin, all were kings of Durin's folk.

Durin's axe survived him and would become a great heirloom of Durin's folk.
